Abstract (en)
[origin: US2009090437A1] Manufacturing heat-treatable wrought metal plate having length, width and thickness directions and an engineering properties gradient along at least one plate dimension. Rolled, extruded or forged wrought metal plate is solution heat treated and rapidly cooled. The cooled plate is aged by heat treatment for time to arrive at different tempers across at least one plate dimension (length or width). Controlled heat-input into the plate along its length direction raises plate temperature above ambient temperature to temperature T1, and a temperature gradient is applied between temperature T2 and T3, wherein T2>T3, across at least one direction of the plate by controlled heat-input into the plate from one side (width or thickness) of the plate to temperature T2 and controlled cooling to temperature T3 from the plate at the opposite side of the controlled heat-input, and ageing the plate while applying the temperature gradient between T2 and T3.
